A composition comprising
- (A) a polymer selected from the group consisting of
- (1) an amorphous, non-chlorinated, maleated polypropylene having an acid number in the range of 15 to 65 and a molecular weight of at least 800,
- (2) an amorphous, non-chlorinated, maleated propylene-ethylene copolymer having propylene units in the range of 60 to 98 mole percent, ethylene units in the range of 40 to 2 mole percent, an acid number in the range of 15 to 65 and a molecular weight of at least 800,
- (3) an amorphous, non-chlorinated, maleated propylene-hexene copolymer having propylene units in the range of 30 to 98 mole percent, hexene units in the range of 70 to 2 mole percent, an acid number in the range of 20 to 65 and a molecular weight of at least 800,
- (4) an amorphous, non-chlorinated, maleated propylene-butene copolymer having propylene units in the range of 40 to 98 mole percent, butene units in the range of 60 to 2 mole percent, an acid number in the range of 15 to 50 and a molecular weight of at least 800,
- (5) an amorphous, non-chlorinated, maleated propylene-ethylene-butene terpolymer having propylene units in the range of 40 to 80 mole percent, ethylene units in the range of 1 to 20 mole percent, butene units in the range of 30 to 60 mole percent, an acid number in the range of 15 to 50 and a molecular weight of at least 800, and
- (6) an amorphous, non-chlorinated, maleated propylene-ethylene-hexene terpolymer having propylene units in the range of 40 to 80 mole percent, ethylene units in the range of 1 to 20 mole percent, hexene units in the range of 20 to 60 mole percent, an acid number in the range of 15 to 50 and a molecular weight of at least 800,
- (B) from 18 to 50 weight percent, based on the weight of component (A), of a nonionic surfactant,
- (c) from 4 to 30 weight percent, based on the weight of component (A), of a primary, secondary or tertiary amine, and
- (D) water.
